Not in the Olympics, but this is why I don't consider NASCAR a sport. 1/2 the guys racing have beer bellies! It takes plenty of skill, both for the driver and his or her crew, to be successful, but give me a break. When it comes down to it, they're still dependent on a car. This is why I don't consider it a sport.
The only reason I'm on the fence about NASCAR, along with many other sports of that sort (BMX, motocross) is that they really do require a lot of physical fitness and sport mindset. The vehicles put the playing field pretty even (like luge, skeleton, etc) but in the end physical fitness of the driver plays a major part.
This could be entertaining...
I've always thought freestyle sexy times should be a sport.
